Yup, there is definitely a clear phase in the shed cycle where it almost doesn't look like they're in shed at all, it'll usually be about two or three days. If she regurged I would advise you to skip a feeding (skip the next feeding, and then just feed her the one after that) to allow the digestive flora in them to regenerate. Otherwise they will have a tough time digesting the meal and will more than likely just regurg again.
